The message of Pa Kent's sacrifice is noble and is a refreshing change from the usual heart attack fate, but the tornado as a device isn't the best I agree.

Clark is 17-18 during the scene, and showed moments earlier in the car that he's every bit his age with the argument with Pa Kent. Clark might be incredibly smart and understand Pa Kent's intention and sacrifice on an intellectual level, but as a typical 17-18 year old, would he have emotionally accepted it? He has demonstrated before that his first instinct is to save lives regardless of any caution. And here we're talking about his dad.

I saw that in the scene... a way more realistic not just the Superman perfect nothing happens....
